Are these to be be found in BMW rev counters of the period? I have a few 6 Series display units that I probably won't ever make use of so might be prepared to let you have one of them to see if you can find/extract the part you need.

Thanks, Just to be clear these come out of the speedometer, not the rev counter which does have different cogs. If you have a spare speedometer I can take it apart and salvage the gears. Let me know whats the cost and I will be in touch. Cheers.

Potentially I can do that. What year/model is your car? Or maybe they are all the same over the years?

I found one of my spare clock assemblies (stamped as 1987 manufactured) and removed the speedo unit. I strongly suspect the cog you are after is the small one pictured here, but this one is definitely only 12 teeth!

Hi, if you're willing to break your clocks and it's the late one, could I get the service indicator light bar? For some reason my light bar is missing and I haven't been able to find one. If you'd be willing to help out I'd appreciate it. :)

Interestingly, it looks to me like the small gear is offered here has 13 teeth (ie as per the originally count suggested by the OP), whereas the one from by my late model set is definitely only 12 teeth.
